The Challenge

1. Reoccurrence of Stuttering
2. Discomfort in Identifying symptoms
3. Limitation in Stabilization stage

The Outcome

1. Children can continuously practice through the service at home or center.
2. Children become a broadcasting creator and use video effects which help them enjoy recording.
3. Sharing diverse tasks for stuttering children to accomplish their fluency practice helps children to experience various situations.


The Process

Background

1. Stuttering, also known as stammering, is a speech disorder. More than 70 million people worldwide stutter.

2. The cause of stuttering is not verified. Linguistic speech disorders are caused by a combination of environmental and psychological factors.


3. The frequency of stuttering is highest between the ages of two and five. Early treatment is therefore necessary.


4. The 20% of children’s stuttering continues even if they became adults. For adults, the fluency can be improved by the therapy.


5. Conventional treatments
The Van Riper’s Stuttering Modification Therapy - MIDVAS
The main goal is to stutter easily and not to speak more fluently.


Fluency Therapy - by Neilson & Andrews, Ryan, Webster
The main goal is to speak more fluently.


Integrated treatment
Combination of The Van Riper’s approach and Fluency therapy.


Problems

Financial distress

Financial distress

“I’ve been receiving cognitive and amusement treatment for two years, and I'm paying almost 10 million won a year, but with a tight income, it's hard to maintain the treatment.”- Ms. M. with a 4-year-old daughter who was diagnosed with a speech disorder by the Department of Neuropsychiatry a year ago.

Psychological distress

Psychological distress

“My stammer forced me to leave the company. After 5 to 6 years of job hunting, I failed to join the company due to stuttering.” - Mr. A(34), who chose to voluntarily quarantine from society due to his lack of confidence by stammering.

High risk of relapse

High risk of relapse

“Other language disorders do not get worse when they are improved, but stuttering is most likely to recur. That's why stuttering is an area where even a speech therapist isn't confident. There are many language therapists, but fewer people who specialize in the stutter.” - Ms. J, language therapist at Severance hospital.


Review Matrix

Review Matrix

From the review matrix, there were fewer services for children and need further assistance from fluency improvement treatment. Also, more participation was required from therapists and counselors since there was a limited number of services.

Interviewed a speech therapist who graduated a Ph.D. program in languages pathology at Ewha Woman's University. She is currently working as a speech therapist at Severance Hospital. In addition, several speech therapists, as well as Dr. Lee who is dean of the Speech-language therapy and aural rehabilitation department at Woosong University, helped our project.

Problem Statement

During the symptom verification phase, the therapist feels the pressure to make sure that the child is not upset. Children sometimes don't want to see themselves checking in on the treatment. Because of the treatment method that contains only fragmentary contents, the specific activity for 'symptom check' is often created by the individual of the therapist.

The therapist performs the filming to observe the patient at the stabilization stage and expects the subject to be aware of this. Some school-age children, however, are not aware that they are being watched. They are uncomfortable with the results of fluency exercises.

Children become content creators

Recently, a single content creator has become popular as a dream for elementary school students.
Children at the Shin’s Speech-Language Clinic who helped this research are also familiar with YouTube video media and want to broadcast themselves.

Chatting

Practice solving problems close to everyday life

Each child will be able to set different goals to help improve their fluency or questions frequently encountered in daily life, and the therapist will evaluate their child's fluency and then prescribe it.


Usability Testing

Test

The results of the study showed that the Tingling Cast service motivated users to participate in treatment and promoted greater awareness of their stuttering, while also teaching them the skills needed to actively learn to maintain their own speech fluency. Speech therapists highlighted the fact that children showed an observably greater interest in participating actively in their therapy sessions. Based on these findings, the use of Tingling Cast can be beneficial in the treatment of speech fluency for, and the language development of, stuttering children. Subsequent studies will be conducted to offer services that can help reduce the psychological stress experienced by speech therapists in their work.
